Louisville said the NCAA "abused" its authority when it disciplined the school for a sex scandal that could result in the loss of its 2013 national basketball championship.

The school also said in a 68-page appeal released Friday that the governing body imposed "draconian" penalties and ignored the school's self-imposed discipline. Louisville banned itself from the 2016 postseason after its investigation uncovered violations.

This is the latest step in a case that began nearly two years ago. Escort Katina Powell alleged in a book that former Cardinals staffer Andre McGee hired her and other dancers for sex parties with recruits and players from 2010 to 2014.
